With over 40 years of experience in developing commercial LED testing instruments, Gamma Scientific is trusted by the world’s leading organizations to provide accurate and reliable results.

Gamma Scientific LED testing systems are built around high performance spectrometers that have been engineered to produce accurate, repeatable measurements in the most demanding production line environments.

With near real-time measurement and powerful analysis software, Gamma Scientific systems are designed to handle 24 hour operation on the production floor. Multiple configurations cover a wide spectral range from ultraviolet to near infrared, and are easily customized to match unique testing requirements.

Custom Configurations for Accurate LED Testing

With over 40 years of experience in designing integrating spheres, Gamma Scientific has the expertise to build custom spheres and sphere systems to meet your testing requirements.

Gamma Scientific Integrating Spheres are available in a wide range of sizes from 25mm to 3m in diameter. Standard configurations are optimized for capturing total flux measurements of LEDs, lamps and luminaires.

All spheres come with either our proprietary polytetrafluoroethylene (PTFE) coating or a specially formulated barium-sulfate coating. The PTFE coating gives >99% reflectance over the UV/VIS/NIR region, and is almost perfectly Lambertian.

Large Integrating Sphere Performance at a Fraction of the Cost

Gamma Scientific’s new optical integrating tube is an affordable alternative for testing your T8 and T12 lamps up to four feet in length.

Proprietary technology ensures that measurements are as accurate as those from a 2 meter integrating sphere, at less than half the price. The table top system is also portable and occupies a much smaller footprint.

When paired with a Gamma Scientific spectrometer and power supply, the integrating tube can capture complete spectral measurements for tube lamps. Integrating tube systems produce accurate and highly-repeatable measurements.

Specially Configured for All of Your LED Measurement Needs

The UDT Model S471-LED handheld optometer is designed for use in a laboratory setting or production environment.

The unit comes standard with a photometric detector and LED holding sockets designed to meet the recommended CIE Publication 127 document on measurements of the luminous intensity (candelas) of LEDs. The sockets accommodate regular, miniature and sub-miniature LEDs and feature a locking flange that snaps firmly into a CIE Condition A or B baffle tube, ensuring precise alignment of the LEDs mechanical axis.

uLED Luminous Intensity Meter

This system combines a high-performance photopic sensor with an intensity adapter and a precision LED socket to provide simple and accurate measurement of luminous intensity in units of candela (cd). The system can easily be configured for either of the CIE-prescribed geometries:

Eigenlite LED Light Sources offer the finest and most versatile controlled light energy technology available. They offer interactive spectral programmability along with NIST-traceable absolute calibrations. Eigenlite™ products save time and money, while reducing the uncertainties associated with the testing and calibration of components and systems.
